A filter system comprising:

• a housing comprising an inlet and an outlet for a fluid;
• a first filter element, comprising a filter medium and embodied as a hollow body, arranged in the housing;
• a second filter element arranged in an interior of the first filter element, wherein the first filter element and the second filter element are arranged coaxially and concentrically to each other about a longitudinal axis;
• the first filter element comprising a first end disk arranged at a first end face of the filter medium arranged at the outlet and further comprising a second end disk arranged at a second end face of the filter medium positioned opposite the first end face, wherein the first end disk comprise a first central opening and extends in an annular shape about the first end face, wherein the second end disk comprise a second central opening and extends in an annular shape about the second end face;
• wherein the second filter element comprises a first end face arranged at the outlet and a second end face positioned opposite the first end face of the second filter element, wherein the second end face of the second filter element is closed fluid-tightly by a cover;
• wherein the second opening in the second end disk of the first filter element is closed fluid-tightly by the cover;
• wherein, between the second end face of the first filter element and the second end face of the second filter element, a seal interface is arranged, wherein the seal interface seals directly the first filter element and the second filter element against each other.
